IEEE 1528-2003

1528-2003 is a technical standard for measuring average specific absorption rate (SAR) in the human head from wireless communications devices. It addresses how to evaluate radiofrequency exposure in a controlled and repeatable way, helping engineers and test labs compare results with greater consistency. For products that transmit near the head, the document supports safety assessment, design verification, and compliance-focused testing within electromagnetic fields and waves applications.

Overview of 1528-2003

This standard defines measurement techniques for determining average SAR in the human head from wireless communications devices. In practice, it belongs to the field of electromagnetic compatibility and exposure assessment, where test methods must be consistent enough to support meaningful comparison between devices. The specification is relevant when a product’s operation places RF energy close to the body, especially in head-adjacent use conditions. 1528-2003 is now marked superseded, but it remains useful as a reference for historical testing and engineering review.

Typical use cases

Typical use cases include laboratory evaluation of handsets, portable radios, and similar wireless devices that may be used near the head. The standard can support SAR measurement workflows that use phantom-based setups, calibrated instrumentation, and controlled positioning to assess exposure levels. It is also relevant for product development teams, compliance engineers, and test houses that need a defined method for comparing device behavior under repeatable RF conditions. 1528-2003 helps align measurement practice across design and verification activities.

Why it matters

This standard matters because SAR testing is central to assessing how much RF energy may be absorbed by the head during normal device use. A clear method reduces uncertainty in compliance decisions and helps manufacturers control design risks early in development. It also supports more consistent procurement and test planning by giving laboratories a common technical basis for measurement. For organizations working with wireless equipment, 1528-2003 provides a practical framework for safety-oriented engineering and documentation.
